Two second-half goals from Jack King put Didcot into the British Gas Business Southern League Division 1 South & West play-off final with a 2-0 victory over Windsor & Eton at Stag Meadow.
In Saturday’s final, they will be away to Totton, who beat Beaconsfield SYCOB 2-1.
Didcot, who had lost twice to Windsor in the league this season, held their own in the first 45 minutes, during which Phillip John was booked for a rash challenge.
The visitors, who preferred new Aussie Matt Trott to Michael Watkins in goal, took the lead on 50 minutes.
Josh Dutton-Black combined with John and the latter was brought down on the edge of the box. King stepped up to take the resulting free-kick and drove an unstoppable shot into the corner past keeper Rob Bullivant.
Windsor pressed hard for an equaliser but left gaps at the back and were made to pay four minutes from time.
Substitute Michael Hopkins broke down the left and his pin-point cross was headed firmly home by King from ten yards to send the big contingent of Didcot fans home happy.
Didcot Tn: Trott, Heapy, Powell, Williams, Parrott, Mortimer-Jones, John (Jack 78), King, Bartley, Osbourne-Ricketts (Hopkins 78), Dutton-Black.
